    These seabed and sea surface light data were collected in the Bay of Brest, Brittany, France, in 2011-2012. R.V. Albert Lucas and smaller vessels were used for deployment and recovery of the seabed light sensor instrumentation. Corresponding time series records of seabed and sea surface irradiance were collected. Water depth above, and water temperature at the position of the sensor were also recorded. The data were collected as part of a project studying the effect of tidal variations in water depth and clarity on the light that reaches the seabed (Roberts et al., 2014; Roberts, 2015). They were collected by Bangor University scientists (primarily E.M. Roberts), assisted by contacts at the Centre d'Etudes Techniques Maritimes et Fluviales (CETMEF, now Cerema) and the Institut Universitaire Europeen de al Mer (IUEM).

    The dataset comprises 6 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Irish Sea and St. George's Channel, Bristol Channel and the Celtic Sea areas including specifically the Nymphe Bank and on the shelf edge in the vicinity of the Goban Spur. The data were collected during April of 1979. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Institute of Oceanographic Sciences Wormley Laboratory.

    A dataset collected by investigators of the University of East Anglia during January - February 2020 in the tropical North Atlantic. Gliders SG620 and SG637 were deployed from the RV Meteor during cruise M161 as part of the EUREC4A oberservational campaign. Glider SG579 was deployed by the autonomous surface vehicle Caravela. All gliders were recovered by the Meteor. SG620 and SG637 occupied a bowtie pattern 10 km across centered at 14'10''N 57'20''W. The two gliders were deployed with CT sails measuring conductivity and temperature and completed 131 and 155 dives respectively. SG579 was deployed at 13'21''N 58'50''W and travelled 200 km to the bowtie over 10 days conducting 75 dives. Once onsite, SG579 conducted a further 220 dives. In addition to a CT sail, SG579 carried a PAR sensor and Wetlabs sensor measuring backscatter, chlorophyll a and CDOM. Data were processed using the UEA Seaglider Toolbox.

    This dataset comprises of hydrographic data from the Thwaites-Amundsen Regional Survey and Network (TARSAN) Integrating Atmosphere-Ice-Ocean Processes affecting the Sub-Ice-Shelf Environment project. CTD and glider data have been collected across a number of RV/IB Nathaniel B Palmer cruises in the Amundsen Sea during austral summer since 2018. The CTD data include conductivity (salinity), temperature and depth alongside auxiliary data including oxygen, fluorescence, transmission and PAR. Seagliders collected CTD, oxygen, fluorescence, PAR and microstructure data. The CTD data support data collected by gliders, ship-based surveys and autonomous underwater vehicles (AUVs). The data were collected to help identify how variations in oceanic conditions may influence the behaviour and stability of ice shelves in the region. The data were collected under the NERC grant NE/S006591/1 and in collaboration with the National Science Foundation in the United States.

    The UK Argo program is an active contributor to the international Argo program, offering a comprehensive data set vital for supporting global oceanographic research. The data set includes a mixture of near-real-time and delayed-mode data collected by profiling floats, quality controlled to operational ocean forecasting standards and to climate research standards respectively. Real-time data are available within 24 hours of the float surfacing, while delayed-mode data become available within 12 months of the profile date. UK Argo floats data are typically managed by the British Oceanographic Data Centre. Argo floats operate in profiling ‘cycles’, normally repeated every 10 days throughout their lifetime. As part of a cycle, floats drift at their parking depth of approximately 1000m for 5 or 10 days, then sink to 2000m before starting their ascent to the surface, taking temperature and conductivity measurements at regular intervals. Since 2012, biogeochemical sensors have gradually been rolled out across a portion of the UK Argo fleet, reflecting the broadening research focus of the international Argo program. The UK Argo data set now includes measurements of dissolved oxygen, chlorophyll fluorescence, optical backscatter, pH, nitrate and irradiance. Moreover, an array of Deep Argo floats have recently been adding observations as deep as 6000m, and deployments have ventured to higher latitudes. The UK Argo data set has a variety of uses, including assimilation into operational weather forecasts in near-real-time to climate and ocean biogeochemistry research with the delayed mode data. In addition to its national efforts, the British Oceanographic Data Centre manages floats deployed by partner nations including Mauritius, Saudi Arabia, Ireland, and Portugal. This collaboration underscores the cross-border cooperative nature of the program, which is fundamental to its world-wide success.
